Question

The triangle JKL shown on the coordinate grid below is reflected once to map onto triangle J'K'L':

Triangle JKL is drawn on a 4 quadrant coordinate grid with vertices J is at 8, 1. K is at 5, 7. L is at 3, 4.

If vertex L' is at (−3, 4), what are the coordinates of vertex J'?
(1, −8) (−8, 1) (−1, 8) (8, −1)

Answer 1

alright, so first, draw this out

Answer 2

L(3, 4) L'(-3, 4). use rule (a, b) =>(-a, b)

Answer 3

you want to get a mental picture of what it is asking out

Answer 4

(8, 1) => using the rule it does into (-8, 1)

Answer 5

(although noticing the function occurring will work as well)

Answer 6

wait can yall break it down im dumb lmao

Answer 7

so, to break it down, first draw it out

Answer 8

we are going to act as though we don't see the function and are just trying to figure it out
